-	   <p>DAVdroid ist von Anfang an als Open-Source-Projekt ausgelegt. Der Quellcode kann jederzeit selbst kompiliert und
-	   die App unter den Bedingungen der GPLv3 verwendet werden. Der
-	   <a href=\"https://davdroid.bitfire.at/source?pk_campaign=davdroid-app&amp;pk_kwd=main-activity\">Quellcode ist verfügbar</a>; die App kann auch
-	   <a href=\"https://f-droid.org/app/at.bitfire.davdroid\">über F-Droid bezogen werden</a>.</p>
-	   
-	   <p>Es bedeutet viel Arbeit, die App zu entwickeln und besser zu machen. Daher haben wir uns entschlossen, sie
-	   auch gegen eine kleine Gebühr in die kommerziellen App-Stores zu stellen. Wenn Sie DAVdroid über F-Droid bezogen haben,
-	   überlegen Sie bitte, ob Sie das Projekt <a href=\"http://davdroid.bitfire.at/donate?pk_campaign=davdroid-app&amp;pk_kwd=main-activity\">mit
-	   einer Spende unterstützen</a> wollen.</p>
